Application filed-November 11, 19 13.

To all whom it may concern Be it known that I, ARTHUR E. NEWMAN, acitizen of Canada, residing at Sheguindah, in theProvince of Ontario andDominion of Canada, have invented new and useful Improvements inSwitches-of which the following is a specification.

This invention relates to switches and more particularly to a switch forcontrolling the multi-circuit of an electrically operated shuttle.

The primary object of the invention is the provision of a structurewherein a series of magnets that control the travel of the shuttle maybe energized successively in one direction and reversed and successivelyenergized in the opposite direction.

Another object of the invention is the provision of a switch wherebythrough the oscillatory motion of a rack bar the magnets will besuccessively energized in one direction and then successively energizedin the opposite direction.

With the above and other objects in view, the invention consistsin theconstruction, combination and arrangement of parts hereinafter set forthin and falling within the scope of the claim.

In the accompanying drawings, Figure 1 is a transverse section through alay or batten showing one of the magnets in place. Fig. 2 is a sectionalview through the switch. Fig. 3 is a detail view showing the rack barcooperating with the gear. Fig. 4: is a side elevation of thecommutator. Fig. 5 is a detail enlarged section through the commutator.Fig. 6 is a plan view of one of the commutator sections.

Referring now to the accompanying drawings in detail, A designates anappropriate form of lay or batten for looms, such lay comprising in thepresent instance, a horizontal plate 1 provided with depending posts 2appropriately spaced apart and having the lower ends thereof pivotedupon alining pivot pins 3 carried by suitable bearings 4. Extendingupwardly from one longitudinal edge of the plate 1 is a vertical flange5 and secured to the upper edge of such flange and surmounting the plate1 in parallelism therewith is a strip of metal 6 preferably composed ofbrass. The lay is equipped with a suitable form of reed 7 through whichthe warp threads pass, as usual, and serves the usual function ofbeating the rilling threads into the fabric as the lay oscillates orswings specification of Letters Iatent.

back and forth. The shed is controlled by heddles operating by anyapproved mechanism.

Secured to the upper surface of the plate 1 between the latter and thebrass strip 6 is a series of electric magnets 10 having the polesthereof in contact with the under surface of the brass strip so thatupon the successive energization of the magnets, the shuttle willtraverse its path of travel.

The magnets 10 are designed to be energized successively or one afterthe other so that the shuttle will be carried from one end of the lay tothe other and upon the shuttle reaching the limit of its travel in onedirection,the magnets are energized in the reverse order so that theshuttle is carried back to the initial end of the lay. For this purposeI employ a commutator comp rising, in the present instance, a disk 12fast upon a horizontal stationary shaft 13 having one end journ-aled inone of the'bearingsi and the opposite end journaaled in a bearing 14alining with the respective bearing 4:, the shaft 13 being coaxial withthe adjacent pivot pin 3. Em bedded in one face of the disk 12 is aseries of bars 15 extending radially of the disk and each tapering fromits outer end toward the center of the disk. These bars are embedded inthe face of the disk and insulated from one another and from the disk asat 16, while the inner ends thereof are formed with openings 17 aliningwith openings in the disk to receive pins 18 having the outer endsthereof equipped with binding nuts 19. Loosely encircling the shaft 13adjacent to the face of the disk carrying the commutator bars is asleeve 20 carrying, adjacent to the disk a radially extending arm 21equipped at its outer end with a brush 22 adapted to wipe over the bars15. The opposite end of the sleeve 20 is equipped with a gear pinion 23with which meshes a rack bar 24: adapted to be reciprocated in somesuitable manner so that the pinion 23 and the sleeve 20 will beoscillated whereby the brush 22 will be moved back and forth over thecommutator bars. Leading from one side of a suitable source ofelectrical energy is a power wire 25 electrically connected with thesleeve 20. In the present instance, this connection is effected throughthe medium of a fluid switch comprising a cup 26 containing a quantityof mercury 27, and a switch arm 28 suspended from a ring 29 looselysurrounding the sleeve, the lower end of the switch arm being immersedin the mercury 27 in the cup. Connected to each commutator bar 15through the medium of the binding nuts 19 and the pins 18 is a wire 30having the free end thereof tapped onto one terminjal of one of themagnets of the series 10 and the free terminals of the magnets aretapped onto a common return Wire 31 leading back to the other side ofthe source of energy and forming with the wire 25 and the wires 30 thepower circuit for the series of magnets 10.

From the foregoing description taken in connection with the accompanyingdrawings, the construction, mode of operation and manner of employing myinvention will be readily apparent. In practice, assuming the rack barto be reciprocating and the sleeve 20 oscillating about the shaft 13, itwill be seen that the commutator brush 13 will move back and forth overthe bars 15. As the brush wipes over the commutator bars when moving inone direction the magnets of the series 10 are energized successively orone after the other and act upon the foremost armature on the shuttle tocarry the latter across the lay. Upon the direction of movement of thebrush being reversed, the magnets are energized in the inverse order andthe other armature of the shuttle acted upon to carry the latter acrossthe lay to its original or initial position.

While I have herein shown and described one referred form of myinvention by way of illustration, I wish it to be understood that I donot limit or confine myself to the precise details of constructionherein described and delineated, as modification and variation may bemade within the scope of the claim without departing from the spirit ofthe invention.

I claim:

A multi-circuit closer comprising a shaft, a disk rigidly secured tosaid shaft and having commutator bars embedded therein, a sleeve looselymounted on said shaft and having one end thereof shaped to form an arm,a gear formed integral with the remaining end of said sleeve, a brushcarried by the outer end of the arm formed on the sleeve and adapted toslide on the bars in the disk, a cup having a quantity of mercuryforming a circuit terminal, a switch arm having one of its extremitiesencircling the sleeve, the other extremity within the body of mercury,and a rack bar co-acting with said gear for giving to the said sleeve anoscillatory movement.

In testimony whereof I afiix my signatur in presence of two witnesses.
